The ESP Timeline (one of the site's most popular features) has been
completely updated to allow the user to select (using the timeline controls
above each column) different topics for
the left and right sides of the display.

Christiane Nüsslein-Volhard and Eric Wieschaus describe genetic mutations affecting the body plan of the fruit fly Drosophila, and identify genes controlling the basic body plans of all animals. These genes will eventually be known as Hox genes.

Louis W. Alvarez, Walter Alvarez, Frank Asaro and Helen V. Michel publish their asteroid impact theory of dinosaur extinction. The theory will not gain widespread acceptance among scientists for several years.

German paleobiologist Adolf Seilacher suggests that most of the Ediacaran fossils discovered in the 1940s are not related to any modern forms. Calling them vendobionts, he argues that they went extinct after the emergence of large predators. Seilacher's interpretation, however, will remain in dispute.

1984

David Raup and Jack Sepkoski publish the controversial claim that mass extinctions are regularly spaced at 26 million years.

Richard Leakey and his team discover Turkana Boy, the most complete Homo erectus fossil yet discovered.

1985

Kenneth Oakley publishes Decorative and Symbolic Uses of Fossils describing, among other things, a hand axe crafted by Homo heidelbergensis featuring a fossil sea urchin, and a fossil urchin set within a bronze locket from a Gallo-Roman temple.

Paleoanthropologists excavate an artifact-rich portion of Cueva de los Aviones in Iberia. Fifty-thousand-year-old perforated and pigment-stained shells from the cave will prompt researchers to argue, 25 years later, that Neanderthals wore both makeup and jewelry.

1986

Norman H. Sleep submits a paper calculating the probability of life forms surviving an extraterrestrial impact in the Hadean Period (first 700 million years of Earth's existence). The paper is rejected on the grounds there would have been no life on Earth yet.

1987

Allan Wilson and Rebecca Cann announce that all humans share a common ancestor who lived in Africa as recently as 150,000 years ago. Because the discovery is based on examination of mitochondrial DNA, the ancestral entity will be given the popular (and somewhat misleading) name of "Mitochondrial Eve." The controversial finding will be supported by another discovery in 2000.

Jenny Clack finds Acanthostega, the most complete Devonian tetrapod yet discovered. It has evidence for functional gills as well as legs, strongly suggesting that animals evolved legs while still living in the water.

Kansas rancher Charles Bonner collects a plesiosaur mother-and-fetus fossil. Nearly 25 years later, O'Keefe and Chiappe will describe this as evidence that that plesiosaurs gave live birth and might have been attentive mothers.

Dhananjay Mohabey discovers what looks like a simple clutch of dinosaur eggs in India. Twenty-three years later, he, Jeffrey Wilson and colleagues will report that the fossil find includes not just sauropod eggs, but a predatory Cretaceous snake that apparently snacked on hapless sauropod hatchlings.

1988

Molecular biologist John Cairns describes experiments suggesting that bacteria facing environmental stress can "direct" their mutations to produce favorable adaptations. Directed mutation will remain a controversial idea, but the possibility that organisms mutate at a greater rate (hypermutation) under environmental stress will gain more acceptance.

Ned Colbert finally completes his definitive species description of the Coelophysis dinosaurs he found in 1947.

Philip Gingerich finds a fossil whale, Basilosaurus in Egypt. It has tiny legs, just inches long, retaining all five toes. Five years later, he will discover an even more primitive whale ancestor, Rodhocetus, with even bigger hind legs, in Pakistan. Eighteen years later, Hans Thewissen will announce the discovery of another missing link in cetacean evolution: fox- like Indohyus found in Kashmir.

ESP Quick Facts

ESP Origins

In the early 1990's,
Robert Robbins
was a faculty member at Johns
Hopkins, where he directed the informatics core of GDB
— the human gene-mapping database of the international human
genome project. To share papers with colleagues around the world, he
set up a small paper-sharing section on his personal web page. This
small project evolved into The Electronic Scholarly
Publishing Project.

ESP Support

In 1995, Robbins became the VP/IT of the Fred Hutchinson Cancer Research
Center in Seattle, WA. Soon after arriving in Seattle, Robbins secured
funding, through the ELSI component of the US Human Genome Project, to
create the original ESP.ORG web site, with the formal goal of
providing free, world-wide access to the literature of classical genetics.

ESP Rationale

Although the methods of molecular biology can seem almost
magical to the uninitiated, the original
techniques of classical genetics are readily appreciated by one and
all: cross individuals that differ in some inherited trait, collect
all of the progeny, score their attributes, and propose mechanisms
to explain the patterns of inheritance observed.

ESP Goal

In reading the early works of classical genetics, one is drawn, almost
inexorably, into ever more complex models, until molecular explanations
begin to seem both necessary and natural. At that point, the tools
for understanding genome research are at hand. Assisting readers reach
this point was the original goal of The Electronic Scholarly Publishing
Project.

ESP Usage

Usage of the site grew rapidly and has remained high. Faculty began
to use the site for their assigned readings. Other on-line
publishers, ranging from The New York Times to Nature
referenced ESP materials in their own publications. Nobel laureates
(e.g., Joshua Lederberg) regularly used the
site and even wrote to suggest changes and improvements.

ESP Content

When the site began, no journals
were making their early content available in
digital format. As a result, ESP was obliged to digitize classic
literature before it could be made available. For many important
papers — such as
Mendel's original paper
or the
first genetic map
— ESP had to produce entirely new typeset versions of the works,
if they were to be available in a high-quality format.

ESP Help

Early support from the DOE component of the Human Genome Project was
critically important for getting the ESP project on a firm foundation.
Since that funding ended (nearly 20 years ago), the project has been
operated as a purely volunteer effort.
Anyone wishing to assist in these efforts should send an
email to Robbins.
